This paper defines an efficient rule for monetary policy as one that minimizes a weighted sum of output variance and inflation variance. It derives several results about the efficiency of alternative rules in a simple macroeconomic model. First, efficient rules can be expressed as 'Taylor rules'...

The present paper provides an overview of recent developments in the analysis of monetary policy in the presence of nominal rigidities. The paper emphasizes the existence of several dimensions in which the recent literature provides a new perspective on the linkages among monetary policy,...

This paper investigates the impact historically of aggregate price shocks on financial stability in the United Kingdom. We construct an annual index of U.K. financial conditions for 1790-1999 and use a dynamic probit model to estimate the effect of aggregate price shocks on the index. We find...

The following arguments are developed: (i) models without monetary aggregates do not imply that inflation is a non-monetary phenomenon and are not necessarily non-monetary models; (ii) theoretical considerations suggest that such models are misspecified, but the quantitative significance of this...

Prevalent thinking about liquidity traps suggests that the perfect substitutability of money and bonds at a zero short-term nominal interest rate renders open-market operations ineffective for achieving macroeconomic stabilization goals. In an earlier paper, we showed that this reasoning does...

We examine optimal and other monetary policies in a linear-quadratic setup with a relatively general form of model uncertainty, so-called Markov jump-linear-quadratic systems extended to include forward-looking variables. The form of model uncertainty our framework encompasses includes: simple...

Prevalent thinking about liquidity traps suggests that the perfect substitutability of money and bonds at a zero short-term nominal interest rate renders open-market operations ineffective for achieving macroeconomic stabilization goals. We show that even were this the case, there remains a...

In an earlier paper (Blinder and Morgan, 2005), we created an experimental apparatus in which Princeton University students acted as ersatz central bankers, making monetary policy decisions both as individuals and in groups. In this study, we manipulate the size and leadership structure of...

What stands out in retrospect about U.S. monetary policy during the Greenspan Era is the ongoing movement away from mechanistic restrictions on the conduct of policy, together with a willingness on occasion to depart even from what more flexible guidelines dictated by contemporary conventional...

Are deflation and depression empirically linked? No, concludes a broad historical study of inflation and real output growth rates. Deflation and depression do seem to have been linked during the 1930s. But in the rest of the data for 17 countries and more than 100 years, there is virtually no...
